Chemical O2-generated aerogel-structured wearable microreactors

-generated wearable microreactor prototype (268 g) achieves high space-time yield, 100% oxygen purity, and maintaining oxygen-supply under physical stress. In vivo trials at 4998 meters altitude demonstrate rapid blood oxygen saturation recovery, effectively alleviating acute hypoxia. This work establishes a materials paradigm that overcomes the trade-off between wearability and continuous-flow microreactor in on-body chemical synthesis.
